OS 10.6 - trouble installing Windows via bootcamp

I am currently trying to install windows for my girlfriend on her new Mac Book Pro, she is running snow leopard 10.6.1

I follow the instructions that bootcamp give, I chose the partition for windows xp sp 2 to be installed on. Everything seems to be going fine but when 'restarting from disk...' appears, it stops and tells me 'disk error'.

I restart via the power button and it either a) reboots into 'restarting...' or b) I hold down alt and up pops 'Machintosh' and 'Windows' I go into windows and I notice that the Windows partition is about 1 gig smaller but it still lets me reinstall and the same things happen again. I go into OSX to verify the windows partition (i read this can sometimes help)

I then did the same thing when installing windows on my iMac, I deleted that 200mb partition, this sorted out all my problems on MY iMac but did not make any difference to my girlfreinds.

I then reburnt the CD but nothing changed.

I then tried to delete the windowd partition through the boot camp partition, but it wouldn't let me and told me to go through Disk Utility. These are my worried with this part of the problem:
1) I can not move the partition, but Im thinking this is because its for windows.
2) If under volume scheme i select 1 will it just delete the windows partition and leave the osx partition perfectly in tact?

So basically, can anyone help me? Hope my post was clear and not too long.

It won't let you? Have you tried running the Boot Camp assistant from OS X? From BC assistant, select create partition, select restore. It should then remove the BC partition you previously created. If it won't work from the BC assistant, you have no other choice but to use Disk Utility from the Snow Leopard DVD.

Also - it appears you're trying to install XP SP2 with a version that's not compatible with Boot Camp. Make sure you read the BC instructions before installing.
